Specification of Letters Patent.

Patented Feb. 2d, 19m? To all whom it may concern: v

Be it known that we, CHARLES H. Lonw and ARNOLD ltun'rsoni, citizens of the United States, the said CrmnLns H. Lonw residing at Lakewood, Cuyahoga county Ohio, and the said ARNOLD ltunrsonl residing at Cleveland, Cuyahoga county, Uhio, have invented certain new and useful Improvements in Pasteurizers, of which the following is a specification.

This invention relates to apparatus intended primarily to be employed in the pas teurization of beer in bottles and it's novelty consists in the construction and adaptation of the partsas' will bemore specifically herematter pointed out. p

In the drawingsl igure 1 is a top plan view of an apparatus embodying the invention; Fig. 2 is a partial vertical section on the plane of the line 2-2 in Fig. 1 and an elevation of the parts back of the section plane-;.-';-I}ig. 3 is 'a plan view of the parts beneath the ppm-3 3 in Fig. 2; Fig. 4 is a vertical circui ar section. through the water pans along the line 4--4 in Fig.3; Fig. 5 is an elevation of the transverse portion and a vertical -sectionof adjacent parts; Fig. 5* is a detail sectional view showing the partition between the two compartments of the casing and the overflows from said coinpart-.

ments; Fig. 6 is a horizontal section on the plane ofthe line 6-6 in Fig. 2 and a. plan view of the parts beneath that plane; Fig. 7 is a detail of the revolving carrier on a small scale; Fig. 8 is an,elevation of the out-side of the apparatus when the parts are assembled and Fig. 9' is a vertical circular section through the pans along the line 99 in Fig. 3.

In the drawings 10 is the shell. or outer casing, of the apparatus made preferably of sections of sheet metal secured together in any usual manner and of a generally circular or polygonal outline in cross section. 9 It is provided with a bottom 11 and top 12 so that it has a cylindrical shape and at one side it is provided with a suitable aperture 13 so that access. may be had to the revolving truck or carrier which it is adapted to contain. At a convenient place on its outer surface it is provided with an oii'set chamber indicated at 14 adapted to contain a portion of the power transmitting mechanism as hereinafter described. T'shaped radial ribs 15 serve to stiffen and strengthen the structure.

At suitable intervals along the bottom of the casing and near its vertical shell, are arranged bearings 20 adapted to support rollers 21 provided with shafts 22. The longitudinal axes of the rollers and their shafts are preferably radially arranged with respect to the vertical axes of the shell 10 and the rollers themselves are preferably trusteconical in shape with their smaller ends pointing inwardly. These rollers are adapted to serve as rolling supports for the revolving truck or carrier on which the beer bottles are placed during the pasteurizing operation.

v The revolving truck or, carrier comprises an innercylindrical or polygonal shell 30,

divided by horizontalv partitions 31 and teeth 36 are adapted to mesh with theteeth of a inion 37 arran ed inthe ofi'set chant ber 14. Beneath the annulus 35 is a projecting annular rib 38 having its lower edge sloping obliquely inward .to engage the frusto-conical surfaces of the rollers 21. This construction prevents the. truck from tipping outwardly and serves tolteep it in circular. adjustment.

The Water sup ly system is arranged immediately beneati the top 12 of the casing 10 and above the. revolving trucknorcarrier.

It comprises a series of pans or chambers 41, 42, 43, 44, 45, 46, and 47 arranged in circular succession and suitably secured to the top or sides of the casingin any usual manner.

Each pan has a perforated bottom 400 each pan communicates with the adjacent pan by means olf lateral apertures indicated at 401. The pans 41, 43, 45 and 47 are somewhat deeper than the others. The pan 44 is supplied with hot water from a suitable source of supply through a pump indicated at 48 and a'pipe 480 leading therefromto the pan. The pans 41 and 47 are each supplied with cold water through pipes 410. and 470 connected to a source of water supply, for instance the city water mains. A pump indicated at 49 and pipe 490 leading there-v from to the pans 42 and 46 serve to keep the cold water in circulation.

A diaphragm or partition 50 vertically arranged across the casing serves to divide the space within the carrier into two compartments. This partition abruptly drops at 51 when it reaches the inner drum 30 of the carrier and extends radially to the outer casing 10,beneath the plane of movement of the geared annulus 35, so that while it divides the bottom portion of the easing into two chambers, it divides only the portion of the casing inside the carrier into two chambers above the plane of such movement. This partition is of any suitable material preferably of sheet metal, but is provided with a sheathing of asbestos or similar nonconducting material indicated at 52. Referring to Figs. 3 and 4, it will readily be seen that this partition practically divides the apparatus into a chamber A substantially coincident with the circular extent of the hot water pan 44 and into another chamber B smaller than this.

The power transmitting mechanism comprises the following parts: 60 is a motor of 7 any suitable size and construction mounted in a housing 61 on the top of the apparatus. 62 is its main shaft carrying a driving pinion 63 adapted to mesh with a spur gear 64 mounted on a shaft 65 on which is secured a miter gear 66 adapted to mesh with a similar miter gear 67 mounted upon and adapted to rotate a vertical shaft 68 located in suitable hearings in the frame of the apparatus. Near its .lower end this shaft 68 carries a pinion 69 which meshes with and drives two pinions one 600 adapted to drive the cold Water pump indicated at 49 and the other adapted to drive the hot water pump indicated at 48, the shafts602 and 603 of these pumps being adapted to rotate in suitable bearings formed in brackets 604 and and 605 extending from a framework 606 which surrounds the shaft 68.

To the upper end of the shaft 68 is secured a pinion 607 which meshes with and drives a gear 608 the shaft 609 of which is provided with a Worm 610 which meshes with a worm gear 611 the shaft 612 of which,

through two beveled gears 613 and 614 rotates a shaft 615 a'rranged outside of the casing 10 and upon the lower end of which is mounted the pinion 37 which meshes with :the teeth 36 of the annulus and so rotates the revolving truck or carrier.

The mode of using the apparatus is as follows: The niot-or 60 is first started to the other side of the door same time cold water is turned into the pipes 410 and 470 from the city mains. The

parts are so proportioned that the carrier revolves very slowly, and in practice in the described apparatus it revolves only once an hour. The hot water pump 48 is then 0011- nected to the source of hot water supply. Preferably the bottom of the chamber A is used for that purpose water being supplied thereto in suitably quantity and heated by steam supplied through a pipe passing into the same, as shown at m in Fig. 8. The hot water is by means of the pump 48- de-' li'vered to the pan or chamber 44; By means of a thermostat stationed at a suitable place in the current of water the steam deliyery can readily be automatically controlled and the water in this pan maintained any desired temperature. This is a usual expedient in the art and needs no further descrfption. The water in this pan should be kept at above a pasteurizing temperature because it parts with some of its heatrapidly as will presently be described. The cold water is delivered to the pans 41 and 47 by the pipes described. The hot water-is delivered to the pan 44. From this latter pan it passes at either end through the apertures 401 to the pans 43 and 45, and when these pans are filled it flows into the pans 42 and 46 where it meets the cold waterfrom the pans 41 and 47. By this arrangement as the bottoms of all the pans are perforated there is a constant spray or series of jets of hot water descending from the pan 44 upon the carrier and consequently upon the bottles which it contains.- There is likewise a similar constant spray of reiatively cold water descending from the pans 41 and 47, and inasmuch as the supply of waten to the pans 41, 44 and 47 is greater than the amount that will'pass through the bottoms of said pans, it will be evident that the water will overflow into the pans 42, and 43, and consequently the waterfrom both the pan 44 on the one hand and the pans 41 and 47 on the other mingle and mix in the pans 42 and 43 on the one side and 45 and 46 on ;the other there is a similar constantly descending spray from each of these pans, the water in the pans 42 and 46 being warmer than that in the pans 41 and 47-and the water in the pans 43 and 45 being warmer than that in the pans 42 and 46 and cooler than that in the pan 44. The water from the pans 41, 42 and 43 on the one side and the pans 4T, 46 and 45 on 13 collects in. the bottom of the compartment B and is raised bythe pump 49 and delivered to the pans 42 and 46. As it mingles in the bottom of the tank it is of about the temperature of the water in these pans and it is there delivered in the interests of economy. It will thus be seen that the hot water in compartment A is constantly in circulation, the water in the pan 44 being kept at a substantially uniform temperature and that the colder water in compartment B is constantly in circulation, but that. there are three zones of falling water on each side of this compartment, being zones of gradually increasing temperatureon. the one side and gradually diminishing temperature upon the other side. Suitable overflows, as a and I),- (see -Fig. 5*) are provided at the bottom of the casing so that the hot and cold water will not pass over the partition 50 and mingle.

The water supply and circulation system having been established and supposing the carrier to be moved in the direction of the arrows as indicated in Figs. 3 and 6,the

workman places the bottles of beer in the.

trays 33 completely filling a vertical series of compartments in the carrier. As the carrier slowly revolves he fills the next vertical series and so on. As the carrier revolves it brings this series of compartments first under the pan 41. This is filled with cold water which is descending in a shower. It would usually be somewhere about 70 Fahr. and would have no injurious effect on the bottles which would probably be at a temperature of from 45 to 55- Fahr. By the time the carrier passed completely through this zbne of descending water the bottles and the beer within them would be of substantially that same temperature of Fahr. As the. carrier continues to revolve it brings the bottles beneath the pan 4-2 and under the influence of the water descending therefrom which would usually be at a temperature of about 90 Fahr. The carrier still continuing to revolve, the bottles are next brought beneath the pan L3 and subjected to the action of the water descending therefrom at a temperature of 120 Fahr. Then passing out of this zone the bottles are brought beneath the pan 44 from which the water descends at a temperature of about 140 Fahr. and they continue to be subjected" to this temperature during the whole time that that portion of the carrier rewlves beneath the pan 4A. In the described apparatus this takes more than half an hour and the beer is completely and thoroughly pasteurized during this travel. As the carrier continues to revolve the bottles pass successively beneath the pan -15 from which the water descends at a temperature of above 120 Fahr. the pan 16 from which it descends at a temperature of about 90 Fahr. and the pan 4:7 from which it dcscends at a temperature of about 70 Fahra, thus gradually cooling it to the temperature of the outside air or of the bottling house. As the series of verticalcompartments containing the pasteurized beer are brought opposite the door 13 the trays 33 with the bottles are removed by the workman who fills the compartments with a fresh lot of bottles-to be treated. The horizontal shelves of the carrier on which the trays 83 rest and the trays themselves are perforated so that the falling water coming from the pans above the carrier passes from one shelf and one tray to the one beneath'it and the bottles are practically in a body of falling water all of the time that they are under treatment.

The advantages of this system of pasteurization are considerable. In the first place it combines the sprayingsystem with a con- 'tmuous operation. The bottles are kept unmoved in substantially the same horizontal plane while passing through the successive zones of treatment and consequently there is no liability of breakage through move ment or handling. The variation in temperature of the beer is so gradual that the. bottles never break because of expansion or contraction. The apparatus is placed. directly on the floor and requires no reconstruction of the floors or walls of thebuilding in which it is operated. But one workman, who may be a boy, or an unskilled laborer, can readily handle all of the bottles and move and handle more than one at a time, usually twenty-seven in a tray so that much time and labor is saved. The water employed can be repeatedly used. The hot water has not lost much of its heat when it reaches the bottom of the apparatus and but little steam is required to restore its initial temperature. The division of the apparatus into two compartments also saves heat. The cost ofthe power to operate the mechanism is much less than that required for moving flexible carriers through large bodies of water. Moreover'the operations being conducted inside of one casing there little escape of heat through conductivity.
